Restoring from Jailbreak Backup

[chrisschlitt]

Ok, So I am a college student at Penn State and we have a limit on the amount of internet we can use per week in our dorms. I went over that limit (ichat uses up SO much bandwidth!) three times and when that happens, my internet is cut off for the rest of the semester

So then I decided that I would just tether my iphone 3gs to my macbook pro unibody. I remembered that I could do this using help.benm.at but that was in the summer and now that my iphone has 3.1.2 I couldn't do that anymore and I couldn't downgrade bc I never jailbroke it before.

I just went ahead and jailbroke my iphone and used the dev team hack to enable tethering (using this video: http://www.youtube.com/watch?v=qIeTLEAKGc8) and it said I was changing the baseband or something? I don't know...

I also just played around with the jailbreak by installing things from cydia like getting backgrounder and things that added different settings like downloading attachments from mail and quickreply for texting and stuff.

Anyway, what I want to do now is unjailbreak my iPhone because my dorm is going to have unlimited wireless internet so here is my question:

Because I changed the baseband and other settings and things, if I restore my iphone to a new fresh 3.1.2 using itunes, can I use the "restore from backup" feature in itunes using a backup that I made when my iphone was jailbroken?

Will this be the same as restoring from a non-jailbroken backup? Should I not do this?

Thanks,
Chris

If you want to unjailbreak... I wouldn't restore from backup. Just do it as a new phone and then re-sync all your apps and stuff. You'll lose any saved games or stuff you have in your apps though, that's the only downside. I think it is the only way to completely remove a jailbreak though.

I was about to give you advice on getting around the bandwidth limits though . At U of I, I found out we could just change our internal MAC address and it would give us a whole new limit. I just switched between my default MAC, which I wrote down so I'd remember it, and a backup MAC, just random numbers that I also wrote down. I switched between 2 so it would look like it was just 2 different computers rather than a new computer every other day.

You may have to google it. On windows it wasn't very hard, but I'm not sure at all how to do it on OSX. I didn't have my mac when I was living in the dorms.
